I'm not currently TTC, but test occasionally when AF is late. I've recently had a couple of Wondfo tests develop bad evaps after five minutes. I'm not talking a shadow, but rather easy-to-see lines with color. The only difference is they tend to be streaky. Of course we know we're not supposed to read tests outside the time window, but it's still unsettling to see a line so clearly after ten minutes.
Just a warning for all of you!
